New portable devices are constantly coming on the market so the list of compatible devices is always growing. Overdrive continually evaluates new devices and updates this list, which can be found here.
Many eBook readers have restrictions on the DRM (digital rights management) required by publishers for borrowing materials. Be sure to check for compatibility before downloading a title.

You can now change the default lending period for digital formats. Click on Account on the North Carolina Digital Library page, and then click Settings from the right-hand menu. Pick the desired lending period for each format.

Unavailable titles have grayed-out format icons in the top-right corner of each cover image. You can place a hold on an unavailable title to be added to the waiting list. Click on a title to open its details page, and then click Place a Hold. If prompted, sign in with your information. Enter your email address and click Place a Hold. When you receive an email notifying you that the title is available, follow these instructions to retrieve your hold.

Yes. The option to renew a title becomes available three days before the title is set to expire for both eBooks and audiobooks. If there are no existing holds on a title, the Renew icon will be green. In this case, you can then borrow the title again immediately once your first checkout expires. If there are existing holds on a title, the Renew icon will be grayed out. In this case, you can still use the renew feature to reserve a spot on the title's wait list so that you can borrow it again as soon as it's available. Once you renew a title, its Renew icon on your library Bookshelf will have a checkmark next to it. You can only use the renew feature once for each checkout.

Audiobooks can be burned to a CD if the publisher has given that permission. Audiobooks can also be transferred to devices, although there might be a limit to the number of transfers and devices. All this information can be found on each titles’ Digital Rights Information. More on that here.

All digital titles are automatically returned to your library at the end of their lending periods, so you never have to worry about late fees. If you'd like to return a title early to make space in your library account, you may be able to do so using the sections outlined here.
